A magnitude 7.8 earthquake struck the Philippines at a subduction zone, making it the largest earthquake of the year. Subduction zones are tectonic plate boundaries where one plate slides beneath another and are capable of generating the most powerful earthquakes on Earth, potentially reaching magnitudes above 9.0. While this earthquake was significant, the subduction zone setting means it could have been considerably larger.
Why it matters
Understanding that subduction zones can produce even larger earthquakes than the 7.8 event highlights the ongoing seismic risk in the Philippines and similar regions. This knowledge is critical for earthquake preparedness, building codes, and disaster mitigation planning in areas near subduction zones worldwide.
